To sum up, there is an interaction between the rail fishplate and the steel rails. The two will rub against each other. The railway fishplate has its own bearing range and the material of the fishplate will affect its own damage. The interaction and time of the two are the main reasons for cracks. We can also analyze the cause from the location of the crack. When the crack is on the top of the railway fishplate, it is more affected by the material. When the crack is in the lower mouth, the load is more affected.
Environmental factors also have a certain impact on railway fishplates. When the weather is cold, railroad fishplates are damaged more often than in other seasons. As the temperature becomes lower, it will affect the tensile stress in the middle of the railway fish plate, thereby causing the fracture of the railway fishplate. However, there are some special-purpose rail fish plates. Due to the particularity of the material, their force range is more complicated and the corrosion resistance will be worse. Therefore, the damage degree will be higher than that of ordinary railway fishplates, so they are more harmful. We should pay enough attention to it and use it with caution.
Rail fish plates are long-term consumables for railway lines. Its timely maintenance and replacement to ensure the normal operation of the railway line.
